Welcome to the miniglider wiki!

This is the first project of the Maritime Robitics Student Society (MRSS).

It is based on the glider design from: http://www.seaglide.net/blog

Changes we are making to the design

  • Add some sort of connection for USB to the outside, so we can attach a short wire for testing.
  • Different bottle

Parts we already have

  • Arduino micro (CapneriK)
  • Continuous rotation servo (FatManSteamboat or Baaswex)
  • shrinkwrap, wiring, pushbutton switch *2 (CaperniK)
  • 9 Volt snap connector (CaperniK)
  • pair of lipo battery connectors (CaperniK)
  • proto board (CaperniK)
  • 10 kOhm potentiometer (CaperniK)
  • 5 Ohm resistor (CaperniK)
  • 3 colours LEDs (smaria)
  • pre resistors for LEDs (CaperniK)
  • pin headers (CaperniK)

Parts that are obvious

  • 9 V battery (smaria)

Parts we are going to order and have a supplier for

Part description supplier partnumber Cost URL

Part that still need attention

Buoyuancy Engine

ca. 100 ml surringe

The plunger needs to be solid, not only a rubber ring, since it is the part that the weights get fitted to.

Weight diameter length volume cost url
77g 3.5 cm 17.5 100 ml £ 1.9 ebay
?? ?? ?? 100ml £1.67 ebay

BB pellets

These need to have a good ratio of weight vs. diameter. |Weight|diameter|cost|No. of pellets |url| |0.3g | 6mm | £17| 2000 |www.amazon.co.uk/Bulldog-Pellets-Weight-Premium-Airsoft/dp/B00BGN9FP6|

Alternative Ideas: Sand. Washers.

Washers might be the best solution!

3d printed parts

depend on surringe

  • attachment to servo
  • attachment to plunger rubber bit + container for BB's if we use them

Bolts and screws

depends on surringe

  • big bolt to go into surringe
  • 3 small screws to attach to servo motor

Bottle
